Photoacoustic imaging technique could reduce nerve damage during surgery

Photoacoustic images of the ulnar and median nerves from a pig
Photoacoustic images of the ulnar (left) and median (right) nerves from a pig recorded in vivo for the first time. The nerves were illuminated with 1725 nm light and overlaid on co-registered ultrasound images. The outlines of the nerves and the surrounding agarose regions of interest (ROI) are shown as well.
